As some of you know, I am a gamer of advanced age in my early 40s. That makes me a veteran gamer around here. My first game system was not the NES, but the Atari 2600 way back in the early 1980s. I first started playing video games at around the age of 10. That would give me a whopping 30 years of video game experience!
One piece of advice I can give to all of you is not to be a fan boy of a particular video game company. My choice of video game consoles were always based on the games that game system provided the most of. For example, it's easy to be a Nintendo fan boy when the NES and SNES were around because they provided a lot of games. But when Nintendo 64 and Gamecube came, it would not be easy to just stick to Nintendo because there were more games available for Playstation, PS2, and Xbox.
The game system I have now is the Wii because I like the games available for it. But if Nintendo releases another system that doesn't do very good, then I will most likely get one of the other system made either by Microsoft, Sony or another company.
Another thing I've learned is that you don't have to have the latest technology in order to have fun. This is what Nintendo has learned. For example, the Wii is not as advanced as the Xbox 360 and PS3, yet many people still find it fun to play. Also, the Nintendo DS has lots of 2D games for it that many people still find fun to play, outselling Sony's more advanced PSP.
